' The auxiliary toilet seat comprises essentially two flexible,substantially tubular, inflatable air cushions, each shaped to conformwith the ordinary toilet seat or commode seat opening. These cushionsare so joined that one is positioned directly above the above.

An object of this invention is to provide an auxiliary toilet seat whichis easily wedged into place on the ordinary toilet or commode seat andis capable of being held against displacement therefrom.

A further object of this invention is to provide an auxiliary toiletseat which is collapsible and useful to those persons who because oftravelling make frequent use of public lavatories.

Another object of this invention is to provide an auxiliary toilet seatwhich is of such a structure that it can be attached to and removed fromthe ordinary commode seat with a minimum of efiort.

still another object of this invention is to provide an auxiliary toiletseat which is easily and quickly cleaned.

Other objects and features of this invention will become apparent-fromthe following detailed description.

Fi ure 1 is a view inperspective of theauxiliary toilet seat.

Figure 5 is a sectional view taken on line 55 of Figure 1.

Figure 6 is a sectional view taken on line 6-6 of Figure 2.

Figure 7 is a view in perspective of a portion of the auxiliary toiletseat which also shows a sectional View taken on line 4-4 of Figure 1.

Figure 8 is a view in perspective of the arm support to be used with theauxiliary toilet seat.

Figure 9 is a sectional view taken on a line, similar to line 5-5 ofFigure 1, in another embodiment wherein the openings of the respectivelyjoined tubes differ in size.

More specifically, the auxiliary toilet seat consists of a flexible,substantially tubular, inflatable air cushion i having an opening ofsubstantially the same size as that of an ordinary commode iii] 2 seat3. Attached to air cushion l at the points A, which are on the bottomportion of the periphery of cushion I, is a second flexible,substantially tubular, inflatable air cushion 2, which may have anopening of substantially the same size as, or

smaller, or larger than the opening of cushion l,

the latter as shown in Figure 9 by tubes I00 and 206. The points A areon the bottom portion of the periphery of the cushion l and. are on aplane K which is tangent to the cushion l at said points A andperpendicular to the vertical lines B B which fall on the vertical axisof the cross section of cushion I and on the vertical axis of the crosssection of cushion 2. Cushions l and 2 have attached thereto valves 4and 5 by means of which they can be inflated or deflated. The

cushions i and 2 can be of oval or circular cross section; The cushions1 and :2 are formed of sheet plastic materials, of sheet rubber, ofrubberized fabric, or other suitable material or substance which isfiexible and normally substantially limp, which is waterproof andairtight, which has a smooth outer surface that will not irritate thehuman skin, and which is easily washable.

Arm supports i0, it (Figure 8) can be attached to air cushion I as shownin Figures 1 and 4. Said arm support means are capable of attachment tocushion l, are formed of any relatively stiif, flexible material such.as plywood or plastic sheet board, and are so made that the baseportion l4 maybe fitted over cushion i and attached thereto by anysuitable means, such as by adhesives. Base portion M of arm I0 is of thesame configuration as the upper half portion of cushion I. These armsupports are utilized in the auxiliary toilet seat for children.

The auxiliary toilet seat is utilized in the following manner:

Air cushions l and 2 are inflated by means of valves 4 and 5. Cushion 2may be referred to as the fastening cushion. Cushion 2 is then wedgedunderneath the commode seat 3, and cushion I thus rests on the commodeseat or adult toilet seat 3, as shown particularly in Figures 3 and 6,whereby the auxiliary seat is held rigidly in place on the commode seat3 and is also held against displacement from said adult toilet seat 3.In other words, the auxiliary toilet seat is wedged into opening of theadult toilet seat 3 which rests at the external junction of the twocushions.
